Question 969241: In testing a certain kind of truck tire over a rugged terrain, it is found that 25% of the trucks fail to complete the test run without a blowout. What is the probability that form 5 to 10 of the next 15 trucks tested have flat tires?

-----
Binomial Problem with n = 15 and P(flat) = 0.25
---
P(5<= x <=10) = binomcdf(15,0.25,10)-binomicdf(10,0.25,4) = 0.3134
